Taurine-pyruvate aminotransferase (EC 2.6.1.77) is an enzyme that catalyzes the chemical reaction.
The two substrates of this enzyme characterised from Bilophila wadsworthia and Rhodobacter capsulatus are taurine and pyruvic acid. Its products are L-alanine and sulfoacetaldehyde. The same enzyme in Paracoccus denitrificans can use hypotaurine, which gives sulfite and acetaldehyde after spontaneous hydrolysis of the initial product. This enzyme is a transferase, specifically a transaminase, which transfer nitrogenous groups. The systematic name of this enzyme class is taurine:pyruvate aminotransferase. It is also called Tpa.
